The computation process that produces observed properties from its input data.
Input data may be an acquisition or some other computatation, not listed here yet.
Each newly computed observed property that this computation can produce is defined as its *capability*.
The list of capabilities is all-inclusive, even though not every computation can engage all capabilities.
